Title: Surface treatment method the apparatus thereof for changing the surface properties of the object without damage by plasma
Inventor: MIYAKAWA TAKUYA
IPC: C23F4/00
Filed: 1996-12-18
Granted: 1999-08-21
Abstract: A kind of surface treatment method which can change the surface properties of the object without damage by plasma and with large degree of freedom of the surface treatment space. In order to increase the wetness of the soft solder of workpiece, the gas material of halogen composite containing carbon fluoride is guided into the plasma generator of the surface treatment unit. At that time, it can also employ the pressure by gas carrier except the helium. The plasma generator can activate the material gas to decomposite by applying low frequency as 0 to 50 KHz of alternating voltage or direct voltage under normal atmosphere pressure and generate the reactive fluorine which is used to contact the surface of the workpiece. Then, because the process did not employ the short life-span fluoride as the main object, the position of workpiece can be freely configured so as to eliminate odor generation. The hydrogen halide can be effectively decomposited in an aquiferous atmosphere under decomposition of halide.

Title: Multicore glass optical fiber and methods of manufacturing such fibers
Inventor: FIACCO RICHARD MICHAEL
IPC: C03B37/012
Filed: 1998-07-23
Granted: 1999-08-21
Abstract: A glass optical fiber includes multiple cores fused into a single fiber. The new optical fiber is coherent, in the sense that the cores maintain their relative position with respect to each other within the fiber throughout the length of the fiber. That is, a core having specific radial and angular positions at one end of the fiber will have the same radial and angular positions throughout the fiber, including at the fibers opposite end. In one aspect of the invention the fiber presents a circular cross section, in another it presents an elliptical cross section of greater eccentricity to ease the task of orienting the cores within the fiber for combination to signal sources, other fibers, integrated optic devices, receivers and other optical components. An orienting core may suitably be included in the fiber to further assist in orienting the fiber end. In manufacturing the new optical fiber, a silica tube is stuffed with core canes. The resultant assembly is then melted or fused, preferably while being drawn under vacuum, to produce an integrated multicore fiber blank which then can be drawn down to a standard diameter fiber using standard fiber drawing techniques. Alternatively, fusing and drawing can be combined is a single step process.

Title: Tape automated bonding film
Inventor: KATA KEIICHIRO
IPC: H01L23/498
Filed: 1998-11-27
Granted: 2000-09-11
Abstract: An area TAB film has a plurality of first lead lines and a plurality of second lead lines on a base film. Each of first lead lines will be electrically connected to each of peripheral electrode pads while each of second lead lines will be electrically connected to each of inner electrode pads when the chip will be mounted on the TAB film. In this TAB film, the first and the second lead lines have a staggered arrangement from each other and are extended in opposite directions. Practically, the distance or the gap between the first lead lines is wider than that of conventional TAB film. Consequently, the TAB film can cope with an increase of the number of pads with a package size kept unchanged and serves to obtain a low cost package as compared with the conventional TAB film.
